4Rapid Breathing
When you are suffering from asthma, your lungs will be constricted. This affects the overall amount of oxygen that your body can take in during each breath. To compensate for this loss, you have to breathe harder and quicker. Thus, rapid breathing might occur and increase the respiration rate. To check for this symptom, just place your hand on the chest and count the number of times it falls and rises in 1 minute. Hold a clock or a stopwatch in another hand to time out precisely. Normally, your usual respiratory rate should be from 12 to 20 breaths per minute. In moderate cases of asthma, this figure would increase up to 20 or 30 breaths each minute. [4]
